Nowhere in the article does it say thatshe comes floating in, glowing and unscathed, and picks up her "poor", overwhelmed "little helper"

That was completely imagined by worrywarts. It's probably not going to happen.

All we know is she carries him out. Who is to say she hasn't been in the fight the whole time, fighting right next to him, bloody and bruised and covered in soot and grime, and when Gandalf is felled she picks him up and retreats. Who is to say she doesn't arrive with an army of elven reinforcements and runs in (not floats), slashing through swathes of orcs to save Gandlaf just before he's overcome by the Necromancer?

Where on earth do you get off assuming she'll float, assuming she'll be unscathed, and assuming it'll be a patronizing scene?

Lord knows the scene you described would be awful, and I'd hate it as much as you, but we have no evidence to suggest that's how it'd going to play out. So stop worrying just a little bit...
